Su Qingluan looked up and saw Xu Kekuan, supported by a servant, standing opposite her with a smile on his face.

She immediately jumped up and tried to support Mr. Xu with the hand that wasn't holding the snack, but he waved his hand away and refused with a smile: "It's just that my hands and feet are a little weak, but it's not to the point where I need two people to support me."

As he said this, he considerately asked the servant to take the bite from Su Qingluan's hand, which made her face feel a little hot.

"Why did you get up? If it's inconvenient, just let someone know and it's done." Su Qingluan felt a little sorry.

She originally just came to visit the patient. If she had to trouble the patient to entertain her personally, wouldn't that be putting the cart before the horse?

Xu Kekuan sat down on a table across from the redwood coffee table and dismissed the servants. "I've been lying in bed for two or three days. My bones are almost falling apart. It would be better to walk around."

Seeing that the servants were busy running around, Su Qingluan was too embarrassed to ask further questions, but she was curious: Didn't the ancients value living together for generations? Why did it seem that there was no younger generation around to take care of them?

Perhaps because she read too much social news, Su Qingluan couldn't help but think to herself: Leaving such an old man alone at home, aren't the family members afraid that the old man will be bullied by evil slaves?

Of course, Su Qingluan was not so lacking in emotional intelligence that she asked such a simple question on her first visit.

However, Xu Kekuan saw what Su Qingluan was thinking and took the initiative to explain:

"Don't worry, my dear Su. Although my daughter is married and far away, my son is only out and will be back in the evening. Moreover, I have a grandson who is studying with Master Zhou. I think he will be back in about half an hour."

Su Qingluan felt slightly relieved, but then she was stunned and touched her cheek: Did she ask it accidentally?

Seeing Su Qingluan's expression, Xu Kekuan couldn't help but smile and said, "Young friend Su has a pure and kind heart. You can tell at a glance."

...Doesn't this just mean that she shows everything on her face? Su Qingluan was speechless.

Wait... Master Zhou?

"Is it the Master Zhou who has a very immortal look?" Su Qingluan asked in surprise.

"Does Su Xiaoyou know Master Zhou?"

Su Qingluan shook her head. "Although we live in Huaxi Village together, I've only met Master Zhou once. I've heard that he's very knowledgeable."

Xu Kekuan nodded. "Who in this area doesn't want their child to study under Master Zhou? But Master Zhou has his own set of rules for selecting students—ahem…"

Halfway through the conversation, the old man coughed a few times, and Su Qingluan hurriedly handed the tea in front of Xu Kekuan to him.

This cough interrupted the old man's words, and also interrupted Su Qingluan's original plan to ask Master Zhou about something - after all, she has a seven-year-old brother. If this Master Zhou is really good, it is equivalent to having a key private school nearby!

However, after such a coughing fit, Su Qingluan could not just pick the topic that interested her, but instead went back to Xu Kekuan's condition.

"What did the doctor say?" Su Qingluan asked worriedly after Xu Kekuan suppressed his cough with tea.

"It is said to be a 'Slow Wind Evidence'."

Su Qingluan knew nothing about Chinese medicine, and her head was full of questions after listening to it.

However, as she inquired carefully about the symptoms, Su Qingluan felt that she seemed to have heard of this symptom somewhere.

"Excuse me," Su Qingluan asked to verify her guess, "is there any food you don't like?"

Xu Kekuan shook his head. "It's not that there's anything I don't particularly like to eat. It's just that I'm getting older and I prefer to eat something that's easier to digest and more refined. Also..."

Perhaps because they met Su Qingluan often and she was young, Xu Kekuan did not hide anything. He told her about his usual eating habits as if he was chatting with her.

The more Su Qingluan spoke, the more she came up with an idea in her mind: If her guess was correct, the old man's illness this time was most likely related to his eating habits.

Mr. Xu doesn't like to eat too rough staple foods, nor does he like spicy vegetables such as garlic. Su Qingluan guessed that this so-called "slow wind syndrome" is most likely what is called "beriberi" in modern times, that is, "vitamin B1 deficiency."

But she was not a famous doctor, and there was no way to explain what "nutrient deficiency" meant in this era, so Su Qingluan couldn't even persuade Mr. Xu to eat more or less.

After thinking for a while, she came up with an idea and said to Xu Kekuan with a smile, "Mr. Xu, I have disturbed you for a long time today. I will come to see you again tomorrow - and then I will bring you some delicious snacks!"

At noon the next day, Su Qingluan came again, carrying a palm-sized bamboo box in her hand.

Xu Kekuan was a little surprised: "How come you have time to come here today, Su Xiaoyou? Didn't you say a few days ago that you would have new products today?"

Su Qingluan blinked mysteriously: Because someone did it for me.

After transferring the recipe of "Jinxiu Thousand Silk Rolls" to "Hongfulou" as agreed, Su Qingluan came up with an idea and simply announced to the public that the new product was bought by "Hongfulou" - although in a sense it was not bad - so if you are interested, please go to the side door of the lobby of Hongfulou.

She suggested setting up a "food pickup point" there so that customers who want to eat by hand can eat the rolled-up "Thousand Silk Roll" directly in their hands, while customers who want to dine in can sit down and enjoy it slowly.

Yang and Su Guangfu once asked Su Qingluan why she didn't put the new products on her own stall. Su Qingluan smiled like a little fox and said, "Because cooking chicken soup, steaming rice, and omelets requires a lot of firewood. It's not only a huge expense, but also troublesome. It's far less time-saving and labor-saving than 'Rolling a Hundred Wealths'."

Therefore, let Hongfulou bear the responsibility of wasting a lot of sunk costs - after all, she is the one who is in charge of the food development, so it would be bad for Hongfulou to not contribute at all, right?

Business matters involved many things, and Su Qingluan's explanation was vague. Xu Kekuan didn't ask too much. He just looked at the bamboo box Su Qingluan brought over and asked, "What is this?"

Su Qingluan opened the box like presenting a treasure. Inside were neatly arranged black balls about the size of longans. Upon closer inspection, it was discovered that the balls were black because they were rolled in a layer of fine black sesame.

"Mr. Xu, this is the tea snack I made!" Su Qingluan said with a smile, "I don't like overly sweet food, so this is not very sweet, but it tastes good. You can try it while you drink tea!"

Xu Kekuan knew from "Juan Baicai" that the little girl in front of him was very good at cooking, so this time he readily took one and put it in his mouth to chew carefully.

Su Qingluan was a little nervous: "Is it possible... that I can't taste it?" She had really thought of many ways to get rid of "that" taste!
